firefly-RK3288非正常死机
本帖最后由 lh2008xp 于 2018-8-2 14:44 编辑运行系统Ubuntu 16.04 LTS，运行代码平台ROS中的Kinetic，工程启动后5分钟左右，死机！通过远程ssh访问的RK3288，ssh全部掉线且无法重连！
如果连接hdmi接显示器，显示器桌面卡死，表现为系统桌面时间不再刷新！
1.死机时RK3288串口打印结果如下：
firefly login: INFO: task sd-resolve:597 blocked for more than 120 seconds.

"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

注意到以上log中有提到 Watchdog detected hard LOCKUP on cpu 0，请问是否是锁死原因造成的原因？
同时提供其他信息以供参考：
2.死机时RK3288温度测试结果,死机后实测芯片温度73.9°C，温度是否过高？
3.死机前CPU使用情况，其中CPU0的软中断（Software IRQ）占用CPU的百分比100%，是否异常？

从串口打印消息Kernel panic - not syncing: hung_task: blocked tasks知道，发生了内核错误！请问这个该如何处理了定位？我仅仅是在现有的RK3288上进行应用开发！
